This invention relates to building constructions and more particularlyto an improved concrete building block adapted to be used about themarginalportions of a window opening.

: An object of this invention is to provide a concrete building blockwhich includes metallic means anchored thereto and to which a metalwindow frame may be-secured so that the window structures in localitiessubjected to termites may eliminate as much wood as possible about thebuilding.

Another object of this invention is to provide an improved buildingblock for use about a window opening which-includes a soft metal stripwhich is anchored to one portion of the block and to which themetalwindow frame may be firmly secured. g

A further object of this invention is to provide [an improved windowframe attaching means in .20 the form of a substantially triang-ularlyshaped strip which is anchored to one side of a concrete building block,the strip having a length substantially equal to the height of the blockso that when a series of these blocks are superposed 925 one uponanother or placed in side by side relation, a metal frame will beprovided to which the metal window frame may be firmly secured.

To the foregoing objectsand to others which may hereinafter appear, theinvention consists 30 of the novel construction, combination andarrangement of parts as will be more specifically referred to andillustrated in the accompanying drawing, but it is to be understood thatchanges, variations and modifications may be resorted to which fallwithin the scope of the invention as claimed. In the drawing: Figure 1is a perspective view of a building block constructed according to thisinvention, and Figure 2 is an enlarged fragmentary horizontal sectionthrough one portion of the block.

Referring to the drawing, the numeral [0 designates generally a concretebuilding block which is provided with an opening I3 through the centerthereof. The block In is provided with a straight inner face H which atone end thereof has a vertically extending recess l2. The outer face Iof the block I0 is substantially straight for the greater portion of itslength and at one 50 end the outer face I4 is rounded off as at I 5.This rounded portion l5 terminates in a concave portion l6 which mergesinto a flat face I I disposed at an angle of substantially forty-fivedegrees to the face l4. One end l8 of the block 55 I0 is inset from theadjacent edge of the angled portion il' as at is, the purpose for whichwill be hereinafter described.

A soft metal strip is adapted to be anchored to the block lll'andcomprises a strip which is triangular in transverse section as'shown inFigure 2. This strip 20 is adapted to be constructed out of lead orother soft metal and in which screws or nails may be threaded or driven.The strip 21'] is anchored to the block l0 by-an anchoring member whichcomprises a stem 2| which ($19 is embedded at one end in the triangularstrip 28. The inner end of the stem 2i is provided with a V-shapedanchoring portion 22 which is embedded in the block l0. Preferably, thestrip 28 is anchored to the block H] at the time the block' H1 is castor is in plastic form.

The triangular strip 20 is adapted to be engaged by'an angle windowframe member 23 which is adapted to be secured to the exposed faces ofthe strip 20 by fastening devices 2 l'ini20 the form of screws or thelike. If desired, a sealing means 25 may be interposed between the angleframe member 23 and the strip 2|].

The outer face l4 and the arcuate portion ii of the block H] are adaptedto have a coating 26 25 secured thereto, this coating being in the formof stucco or the like. A plaster 2! is adapted to be mounted on the endface l8 of the block 10, the plaster 21 having a thickness substantiallyequal tothe depth of the insert portion of the end face I I8 so that infinished form a smooth end face will be provided on the block I. Awooden strip 28 is adapted to be mounted in the recess 12 on the innerside of the block l0 and a channel member 29 is used to receive theslide members of a Venetian blind which are adapted to engage in thechannel member 29. The channel member 29 is secured to the verticalstrip 28 by fastening members 30.

A second wooden strip 3 l is secured to the, inner 40 face ll of theblock l0 and to the strip 28 and plaster 32 is adapted to be mounted onthe inner face ll of the block I0 and if desired may cover the innerface of the strip 3| and the inner edge of the strip 28 and also extendin the space between the inner edge of the channel 29 and the inner edge.of the strip 28 as shown in dotted lines members 2l--22 will be firmlyanchored in the body of the block Ill and the inner face of the strip 20will snugly engage the angled face portions ll of a block l0.

When these blocks are placed on opposite sides of the window opening insuperposed relation, a pair of vertically disposed soft metal stripswill be provided to which the window frame member 23 may be secured.These blocks It may be also mounted across the upper edge of the windowopening and if desired, may also be mounted on the sill or lower portionof the window opening. Where this is done, a substantially continuoussoft metal strip is provided entirely around the window opening to whichthe window frame may be secured.

What I claim is:

1. In building construction a non-metallic wall block having an outerside face formed with an inset forward portion and an outer end faceformed with a portion inset with respect to the outer part of saidforward portion, a soft metal strip positioned against said forwardportion, and

1 means for anchoring the strip and block together.

2. In building construction a non-metallic wall block having an outerside face formed with an inset forward portion and an outer end faceformed with a portion inset with respect to the outer part ofsaidforward portion, a soft metal strip positioned against said forwardportion, and means for anchoring the strip and block together, saidstrip corresponding inwidth and length to the said inset forward portionand having an edge flush with a party of said end face.

3. In building construction, a hollow concrete wall blockhaving an outerend face provided with front and rear rabbets, said block having anouter side face formed with a non-inset rear portion and an inclinedinset forward portion merging into said end face at one side of said,front rabbet, a soft metal strip of triangular cross section disposedthroughout said inclined portion and inset with respect to the saidnon-inset portion, and means for anchoring said strip to said block.

4. In building construction, a hollow concrete Wall block having anouter. side face formed of a non-inset rear portion and an inclinedinset for- 'ward portion, a soft metal strip of triangular 5. Inbuilding construction, a hollow concrete 5 wall block having an outerside face formed of a non-inset rear portion and an inclined insetforward portion, a soft metal strip of triangular cross section disposedthroughout said inclined portion and inset with respect to saidnon-inset portion, and Y-shaped means'having its V and a portion of itsstem embedded in said block and the remaining portion of its stemembedded in said strip for anchoring the latter to the block.

6. In building construction, a hollow concrete wall block including anouter end face and an outer side face, said outer side face being formedof a substantially straight rear portion, an in-- wardly extendingrounded intermediate rear portion, an inset concaved intermediate frontportion and. an inclined inset forward portion dis posed at an angle tosaid concaved portion, said straight portion merging into saidroundedportion, said rounded portion merging into said concaved portion,said concaved portion merging into said inclined portion, said inclinedportion merging into one side of said'end face, a soft metal strip oftriangular contour seated'throughout against said inclined-surfaces andflush with one side of said outerend face, and means. embedded in theblock and strip for anchoring them together.

'7. In building construction, a holl'ow concrete wall block having anouter end face and an outer side face, said outer side face being formedwith a straight, portion, an inwardly extending'curved portion mergingat its rear side into the forward side of said straight portion and aninclined portion merging at its'rear sideinto-the forward side of thecurved portion and at its outer side. into one side of saidv outer endface, said inclined portion being inset with respect to said straightportion and disposed at an angl'eto said curved portion, va'soft metalstrip of triangular cross section disposed throughout said-inclined 45'
